Taiba N’Diaye Wind Power

Audit Analysis

The Taiba N'Diaye Wind Power project uses a standard VCS methodology (ACM0002 v20.0) with a jurisdictional baseline and a VVB-confirmed combined additionality test, giving it a sound methodological foundation. However, the project delivered roughly 7.8 times the pro-rata ex-ante expectation for the elapsed monitoring period, and the verification report lists 19 material findings including a two-month meter calibration delay and inconsistent meter readings versus invoices, which together raise meaningful over-crediting and data-reliability concerns. Documentation quality is further weakened by low extraction confidence and numerous internal inconsistencies (e.g., erroneous 'solar' references in a wind project).

Project Description

Red Flags

• ⚠The monitoring report (2025) reports 239,354 tCO₂e for a single 12-month period, while the validation report (2022) estimated 307,939 tCO₂e over the full 10-year crediting period — the project delivered approximately 777 % of the pro-rata expectation, a discrepancy that demands a clear explanation (project expansion, superior wind resource, or conservative ex-ante modelling).
• ⚠Nineteen material findings were logged in the verification report, including a two-month delay in meter calibration at the SENELEC substation and an inconsistency between official meter readings and invoices (resolved as within meter error), which undermines confidence in the accuracy of the verified ERR.
• ⚠The monitoring report (Nov 2025) states that benefit sharing is not described, contradicting the earlier verification report (Nov 2023) which confirmed it was described — the more recent document is privileged, but the inconsistency signals weak stakeholder-accountability documentation.
• ⚠Multiple internal documentation errors were flagged, including erroneous references to a 'solar' project in a wind-power document, an inconsistent project title, and missing turbine technical specifications for all 46 units.
